IMPROVEMENT 1N CARBURETERS.

Specification forming part of Letters Patent No. 156,463, dated November 3, 1874 5 application filed July 2e, 1874.

I to whichit most nearly appertains to make and use my said invention without further invention or experiment.

My invention relates to Certain improve ments in that class of machines which are employed to saturate air with the vapor of the light hydrocarbon oils for the purpose of producing an illuminating gas, these machines being known as carbureters; and my invention consists in the particular Combination and arrangement of parts hereinafter described.

Referring to the accompanying drawing' for a more com plete explanation of my invention- Figure l is a perpective view, with a portion broken away. Fig. 2 is a section of the valve-chamber, showing the valve. Fig. 3 is a bottom View, showing the pipes P.

A is the outer or Containing vessel, for holding the liquid; and B is an interior airchamber. The outer vessel is kept filled with liquid from a reservoir by means of a pipe,

`D is provided with a valve, i, which closes upward. A long stem, G, extends downward from this valve, and is provided With a float, H, Within the containing-chamber A.

By the operation of this float the valve i is closed, and the iiow of liquid stopped whenever the chamber is filled to the desired height.

Air is furnished to the machine by a suitable apparatus 5 and is conveyed from the receiver (not shown) to the air-chamber B by a pipe, K. From the top of the air-chamber pipes L lead to the bottom of the chamber A, where they enter the conical perforated or wire screens R, which serve to distribute the air throughout the liquid, so that it becomes thoroughly saturated with vapor from every part as it rises to the surface. As the air or gas rises to the top of the vessel A, it is allowed to pass up, through the pipe M, into the gasometer N. From this gasometer the gas is passed out, through the pipe 0, to the distributing-main.

As the liquid becomes relieved of its more volatile portions it acquires a greater specific gravity, settles to the bottom, and ceases to be valuable for producing purposes,but can still be utilized for mixing with the more volatile portions, and occupying a portion of the space, so that it will not be necessary to introduce so much fresh liquid as would be the case if all of this heavy portion were Withdrawn.

For the purpose of concentrating the heavy liquid at the bottom, I employ pipes l? beneath the bottom of the chamber A, which receives a part of this liquid as it settles.

In orderto stir it up, and mix it thorough ly With the lighter liquid in the vessel A, I open the stop-ook E at Certain periods, and allow the fresh liquid to enter the pipe F. This pipe connects with the pipes P, and the Current of new liquid being admitted under the heavy residue, has the effect to force upward all the heavy residue, and mix it with that contained in the reservoir A above. This can be done at any time desired or needed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The carbureter as above described, and

consisting of the pipe C, receiver D, with,

its upwardly-closing valve z, rod G, and iioat H, within the chamber.A, in combination with reservoir B, with the pipes L L, having the perforated screens R, the conducting-pipe F, and the pipes P, all constructed and arranged substantially as and for the purpose LOUIS MARKS. '[L. s]
